PROGRAM MEMORY (ROM)
The program memory is a mask ROM. 1 word of ROM is composed
of 10 bits. ROM is separated every 128 words by the unit of page
(addresses 0 to 127). Table 1 shows the ROM size and pages. Fig-
ure 10 shows the ROM map of M34514M8/E8.

A part of page 1 (addresses 0080
16
to 00FF
16
) is reserved for in-
terrupt addresses (Figure 11). When an interrupt occurs, the
address (interrupt address) corresponding to each interrupt is set
in the program counter, and the instruction at the interrupt address
is executed. When using an interrupt service routine, write the in-
struction generating the branch to that routine at an interrupt
address.
Page 2 (addresses 0100
16
to 017F

) is the special page for sub-
routine calls. Subroutines written in this page can be called from
any page with the 1-word instruction (BM). Subroutines extending
from page 2 to another page can also be called with the BM in-
struction when it starts on page 2.
ROM pattern (bits 7 to 0) of all addresses can be used as data ar-
eas with the TABP p instruction.
